Title: Low pressure die casting apparatus
IPC: B22D18/04
Filed: 1972-10-10
Abstract: A method of low pressure die casting in which molten metal is forced upwardly from a furnace into a die through a riser tube extending below the level of the molten metal in the furnace by gas pressure applied to the surface of the metal. To avoid the formation of oxides in the metal, an inert gas, heavier than air, is introduced into the riser tube adjacent the die to fill the riser tube above the level of the metal in the furnace. On application of gas pressure to the molten metal in the furnace, as the metal rises in the tube, the inert gas expels out from the die cavity. After solidification of the metal in the die and removal of the gas pressure to the furnace, excess molten metal falls back by gravity into the furnace, the inert gas again filling the space above the metal in the tube to prevent ingress of air at the interface between the sprue orifice of the die and the riser tube. A low pressure die casting apparatus is disclosed which includes an apertured cap on the riser tube for engagement with the sprue orifice, the cap being provided with an inlet for an inert gas.

Patent ES-438636-A1 (ES)
Title: System for the safe handling of pulverized coal
IPC: C10L5/00
Filed: 1975-06-17
Abstract: A system for the safe handling of pulverized coal, which system includes conventional coal pulverizing and drying equipment, with cyclones and bag filters added, the latter serving to separate the fine coal from the conveying gas (usually air) and explosion suppression and fire suppression systems, both of which latter systems include conventional components. All three of these systems (coal preparation, explosion suppression and fire suppression) are so combined as to effect the grinding of raw coal whereby to dry and collect the pulverized coal in a oxygen containing atmosphere without property loss due to explosion or fire. A number of explosion detectors and associated extinguishers are strategically located throughout the coal preparation system so that when pressures slightly above operating pressure begin to develop, the explosion extinguishers will be actuated not only to suppress the explosion but also simultaneously to shut down the coal preparation system. Similarly, fire detectors and associated extinguishers are also strategically located throughout the system so that when temperatures slightly above process temperature are sensed the extinguishers will immediately act to suppress the fire and simultaneously shut down the coal preparation system. Preferably the fire suppression system will go into actuation prior to the explosion suppression system and when this happens, the explosion suppression system may be shut down manually if the operator decides it will not be needed, whereby to avoid the expense of having to reload the explosion suppression system.

Title: Synchronizing an oscillator from a television signal
IPC: H04N5/12
Filed: 1980-08-01
Abstract: In a television signal receiver the synchronizing signal is separated at 2, and applied to a pulse shaper 3 to provide discrete pulses coincident with the synchronizing pulses. These discrete pulses are applied to phase discriminator 4 along with pulses derived from an oscillator 7, controlled by the output of the phase discriminator 4. The oscillator 7 produces a pulse train which is frequency divided in a divide-by-20 stage 8 and a divide- by-2 stage 9 to produce pulses at line frequency which are applied through the normal closed contacts of a switch 11 to the input 6. During the period in the field blanking interval when the pre- and post- equalizing pulses of twice line frequency are present the switch 11 provides a path between the output of divider 8 and input 6 to apply twice line frequency pulses to that input. The action of the switch 11 is controlled by a gate 12 controlled from the television signal. The arrangement accelerates pull-in synchronization of the oscillator 7 during the field blanking period.
